This function works exactly as curl_global_init(3) with one addition: it
allows the application to set callbacks to replace the otherwise used internal
memory functions.
This man page only adds documentation for the callbacks, see the
curl_global_init(3) man page for all the rest. When you use this
function, all callback arguments must be set to valid function pointers.
The prototypes for the given callbacks should match these:
- void *malloc_callback(size_t size);
-
To replace malloc()
- void free_callback(void *ptr);
-
To replace free()
- void *realloc_callback(void *ptr, size_t size);
-
To replace realloc()
- char *strdup_callback(const char *str);
-
To replace strdup()
- void *calloc_callback(size_t nmemb, size_t size);
-
To replace calloc()
